Add Hot Shot to old oil tank?

    Hot Shot good idea?

    Home owner here. Got an old oil tank. Old enough that it doesn't have the sheet metal flanges on the end of the tank. I'm guessing it is from the 1940's. Oil contractor dumped a bottle of Hot Shot in it last winter when he did a tune up and cleaning. Two months later I had to replace the standard outlet oil filter and removed and washed the pump inlet strainer. After the summer tune up he suggested that I do more Hot Shot to continue removing the sludge in the tank.

    Is it better to let sleeping dogs lie and not remove the existing sludge, or try to remove the sludge and see if the tank springs leaks?

    If it does make sense to remove the sludge, would it make more sense to recirculate the oil thru a separate pump and filter to clean the tank?

    I've seen it where the only thing keeping the tank from leaking is the sludge in the bottom...

    If it's that old replace the tank.

    1940's oil tank

    I am a burner tech for an oil company and belive me you do not want to deal with an oil spill in your home. Costs could be 100's of thousands of dollars. My advice, get prices to install new tank. At 50+ years old, you got your money's worth out of the old tank. Change it before it leaks.
